With Stabino®, mapping of nanoparticle zeta potential versus fluid parameters is quick. Associated aggregation can be spotted with a NANO-flex size measurement. Complementary, nanoparticle tracking with ZetaView® is ideal for low concentrations. Advances in nanoparticle measurement techniques like these are needed for naturally occurring as well as human-generated nanoparticles. The interdependence between nanoparticles and their surrounding fluid can be studied with particle charge / polyelectrolyte titrations. Stabino® with its titration efficiency opens a new field of particle charge finger printing.
Viewing the number of upcoming questions regarding new materials, selection criteria like reliability, applicability, information content and speed of the measurement techniques become important. With its remarkable colloid analyzers Particle Metrix is in a good position for efficient nanoparticle characterization.
Comprehensive nanoparticle characterization
PARTICLE METRIX Stabino®, NANO-flex and ZetaView® offer complementary answers and extraordinary benefits. Size and zeta potential distributions as well as particle concentration can be measured in widest ranges of size, concentration and conductivity.
An additional instrumentm the Zeta-check, measures the the actual charge of dispersions and macromolecular solutions
from 0.3 nm up to 100 µm particle size, within seconds.
Nanoparticles occur as proteins, colloids in beverages, extracellular vesicles, exosomes, humic acids, liposomes, nano-bubbles, inks, metal oxides, metal colloids, antibacterial silver, polyelectrolyte solutions, chitosan, nano-additives, glass, ceramic and diamond slurries, filtrates.
Nanoparticles are the subject of various activities like reagglomeration control, functional end group formulation, core shell design, colloid stability optimization, dispersing efficiency development, optimum coating applications. In clinical biochemistry and water research the concentration of nanoparticles is an important parameter.
